The invention provides a structural color sun contact lens, comprising a lens, the center of the lens is a pupil area, the area outside the pupil area is a non-pupil area, at least a photonic crystal structure is designed in the pupil area, and at least The pupil area is distributed with photochromic material and/or thermochromic material, and the photonic crystal structure forms a structural color pattern in the solar contact lens. The structural color sun contact lens can not only bring consumers a colorful life experience, but also can effectively block visible light of a specific wavelength, and when the light is too strong or the temperature is too high, the pupil area of the contact lens can change color in time to reduce light transmission. Wear glasses, so as to timely and effectively protect the eyes from strong light radiation and maintain eye safety. |
